The Top-Down Depth Engine is a basic top-down game engine with a unique purpose: To implement DEPTH and HEIGHT.
By adding a height and jumping mechanic to an overhead view, an entirely new gameplay is added. Add jumping puzzles, secret entrances/exits, and hide secrets in places you weren't able to before! Have enemies shoot over or under you! Hide behind blocks! The possibilities are endless.
